If you mean China Renmin University, I'll just say it.

Small languages, that is, foreign language colleges, have many restrictions on majors that can take double degrees, such as customs and journalism.

Economics and finance will not give you a minor or a double degree (a double degree of the National People's Congress refers to reading another degree after the existing undergraduate degree, which is roughly equivalent to the concept of graduate students)

First of all, you don't have this ability. It's hard to study for a bachelor's degree in economics for four years, especially for the courses of the National People's Congress.

Many other universities get two degrees in four years, which can only be said to be mixed degrees.

Second, it is unfair. The score of economics college entrance examination is very high. You will get a degree after graduating from economics for four years. Do you still have a double degree?

For German and Russian, it is more difficult to say that there is no language, but in terms of application, German is obviously much more extensive than Russian.
